Hello All, Thank you for the replies. I read the url and I think I did it all as discribed. I did a ssh into the synology and changed the owner and group for the volume I created and the folder I'm sharing with NFS. I did the the mounting test on the engine and also on the node. And I unmounted it afterwards. But I will try and log on with the vdsm user. Have to look for the password and then I will try and mount again. Kind regards.

Are the user group and permissions set correctly vdsm:kvm?

The storage is mounted on the nodes not the engine.

have you unmounted the storage after your test?

Good Luck,

Hello,

I'm setting up a 3 node cluster with the ovirtnode iso and a seperate server with the engine on and a synology for nfs storage.

I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong.

Any idea's on how to figure this out ?

When you added the permissions on the NFS export did you map the user and group ID to those names? IE the userid is 36? ________________________________ From: Andy Michielsen <andy.michielsen@gmail.com> Sent: Tuesday, July 2, 2019 9:29 AM To: Staniforth, Paul Cc: users Subject: [ovirt-users] Re: Using a synology as an nfs storage Hello, I'm still strugling with adding a nfs share from my synology share.

Hello, I got it working after changing the permissions from the shared folder from 777 to 755 ? Wasn't expecting that. So to get a DS1219+ providing a NFS share for my oVirt environment and this is how I did it. First create the volume and the NFS share in the synology. Create a user vdsm and a group kvm. And then the magic happens on the commandprompt from the synology. SSH into the synology and change the uid and gid to 36 in the /etc/passwd file for the user vdsm. Also change the gid in the /etc/group file to 36 for the group kvm. Then change the permissions for the created share, in my case volume1, to 755 instead off the 777+ synology gives. Restart the nfs server in the ssh session with synoservice --restart nfsd. And thank you all very much for the assistance. It put me on the right track. Kind regards.

Hi,

everything look good.

I would prefer to hostnames (not asterisk) in /etc/exports

[root@ovirtnode005 ~]# showmount -e ovirtstorcl001.get.be Export list for ovirtstorcl001.get.be: /volume1/GETQUADATA001 *

my /etc/exports would look like this:

/volume1/GETQUADATA001 ovirtnode001.get.be <http://ovirtnode005.get.be> (rw,async,no_root_squash,no_subtree_check) ovirtnode002.get.be (rw,async,no_root_squash,no_subtree_check) ovirtnode003.get.be (rw,async,no_root_squash,no_subtree_check) ovirtnode004.get.de <http://ovirtnode.004.get.de>(rw,async,no_root_squash,no_subtree_check) ovirtnode005.get.be(rw,async,no_root_squash,no_subtree_check)

Don’t forget to reexport:

# exportfs -ra

The jumping point here is, could you create directories with (SPM Host) on that location with vdsm user?

[root@ovirtnode005 ~]# sudo -u vdsm mkdir /mnt/nfs/xx [root@ovn-elem tmp]# ls -lad /mnt/nfs/xx drwxr-xr-x. 2 vdsm kvm 6 3. Jul 05:19 /mnt/nfs/xx

Wow. Good to know. It is actually a really bad and misleading error message. Why don't you open a ticket for it? It should be really easy to fix but might save some people a lot of time trying to figure it out. Fil On Wed, Jul 3, 2019, 3:19 AM Andy Michielsen <andy.michielsen@gmail.com> wrote:
